Probability

2. When a dice is thrown, we have 36 the possible outcome.

1. On tossing a coin the possible outcomes are that of a head or a tail. So, the angle space of tossing a coin three times is

S = {HHH, HHT, HTH, THH, TTH, THT, HTT, TTT}

Mutually exclusive events are events that cannot occur at the same time. we commonally call these events disjoint events also. AS per the definition given in the class 11 math probability chapter;

Two events A and B are said to be mutually exclusive if: P (A? B)=0

For Example:
When rolling a single die:

Let event A = getting 2 on top

Let event B = getting 3 on top

Since the number on the top cannot be 2 and 3 at the same time, So A and B are mutually exclusive events.

Conditional probability is the probability of an event occurring given that another event has already occurred. 

It is denoted as:

$P (A|B) = \frac {P (A \cap B)} {P (B)} \quad \text { (provided } P (B) > 0\text {)}$

Where

P (A|B):  is the probability of event A occurring given that event B has occurred.

There are several other concepts which are really impoertant for acing the chapter, We recommend students to use our NCERT Solutions for Probability for the conceptual clarity and doubt solving.

Chapter 14 Probability carries a weightage of around 8 -10 marks in class 11 annual exam of mathematics, which itself is proof how important is this chapter.
